This refreshing marinated cucumber, onion, and tomato salad is a perfect side dish for any meal. The crispness of the cucumbers, the sharpness of the onions, and the juiciness of the tomatoes come together beautifully with a simple yet flavorful dressing.
If you don't usually have red wine vinegar in your pantry, it's worth picking up for this recipe. It adds a tangy depth to the dressing that complements the fresh vegetables perfectly. You might also want to ensure you have a good quality olive oil on hand, as it forms the base of the dressing.
Ingredients for Marinated Cucumber Onion and Tomato Salad
Cucumbers: Fresh and crisp, they add a cool crunch to the salad.
Onion: Adds a sharp, pungent flavor that balances the sweetness of the tomatoes.

Technique Tip for This Recipe
To enhance the flavor of the cucumbers, onions, and tomatoes, consider letting the salad marinate for a longer period, such as 1-2 hours in the refrigerator.

Additionally, you can add a pinch of sugar to the dressing to balance the acidity of the vinegar.

How to Store or Freeze This Salad
- To store your marinated cucumber onion and tomato salad, transfer it to an airtight container. This will help maintain the freshness and prevent any unwanted odors from seeping in.
- Place the container in the refrigerator. The salad will stay fresh for up to 3 days. The cucumbers and tomatoes may release some water over time, so give it a quick toss before serving.
- If you want to extend the shelf life, consider storing the dressing separately. Combine the vegetables and dressing just before serving to keep the salad crisp.
- Freezing this salad is not recommended. The cucumbers and tomatoes have high water content and will become mushy upon thawing, compromising the texture and flavor.
- For a quick refresh, you can add a splash of red wine vinegar or a drizzle of olive oil before serving leftovers. This will revive the flavors and give it a fresh taste.
- If you have leftover onions, they can be stored separately in a small container and used in other recipes like soups or stir-fries.
How to Reheat Leftovers
Embrace the chill: This marinated cucumber onion and tomato salad is best enjoyed cold. Simply transfer the leftovers from the fridge to a serving bowl and give it a good toss to redistribute the dressing.
Room temperature revival: If you prefer a slightly warmer touch, let the salad sit at room temperature for about 15-20 minutes. This will take the edge off the chill without compromising the fresh, crisp texture of the vegetables.
Gentle microwave nudge: For those who enjoy a warmer salad, place the salad in a microwave-safe bowl. Microwave on low power for 20-30 seconds. Be cautious not to overheat, as this can make the cucumbers and tomatoes soggy.
Warm dressing trick: Heat the olive oil and red wine vinegar dressing separately in a small saucepan over low heat until just warm. Pour the warm dressing over the cold salad and toss gently. This method warms the salad slightly while maintaining the crispness of the vegetables.
Quick sauté: For a unique twist, quickly sauté the salad in a hot pan for 1-2 minutes. This method will slightly soften the onions and tomatoes, giving the salad a different texture and flavor profile while still retaining some crunch from the cucumbers.
